Uniqueness Guaranteed: Every item is one-of-a-kind, making them ideal for all projects or designs. Avg. Size Range: (3 to 6 Inches Tall) Sizes Vary Calcite is a mineral that forms mostly in limestone deposits and caves, and can exhibit a wide range of colors depending on the impurities and trace elements it absorbs from the surrounding area. Honey calcite derives its color from iron ions caught in the crystal lattice while it forms. The way these ions are distributed will affect the specific shade of yellow, and some crystals may appear more yellow when viewed from specific directions. Handmade items vary in size, shape, and color when selected randomly (the highest quality items are chosen first). They'll be as beautiful as those in the photos.
